T1/E1/J1 FRAMER/LIU COMBO - ARCHITECTURE DESCRIPTION
The Transmit Single-frame Synchronization signal of Channel 0 pulses HIGH for one clock cycle at the first bit
position (F-bit of channel 0) of the multiplexed data stream with data from Channel 0-3 multiplexed together.
The Transmit Single-frame Synchronization signal of Channel 4 pulses HIGH for one clock cycle at the first bit
position (F-bit of Channel 4) of the data stream with data from Channel 4-7 multiplexed together. By sampling
the HIGH pulse on the Transmit Single-frame Synchronization signal, the framer can position the beginning of
the multiplexed DS1 frame. It is responsibility of the Terminal Equipment to align the multiplexed transmit serial
data with the Transmit Single-frame Synchronization pulse.
Inside the framer, all the "don't care" bits will be stripped away. The framing bits, signaling and payload data are
de-multiplexed inside the XRT86VL3x and sent to each individual channel. These data will be processed by
each individual framer and send to the LIU interface. The local Terminal Equipment provides a free-running
1.544MHz clock to the Transmit Serial Input clock of each channel. The framer will use this clock to carry the
processed payload and signaling data to the transmit section of the device.
Figure 81
shows how to connect
the Transmit multiplexed high-speed Input Interface block to local Terminal Equipment.
Figure 85
shows the
timing signal when the transmit framer is running at 12.352 Bit-Multiplexed Mode
